Ive read somewhere that the NC10 has a multitouch touchpad, but i cant get it to work on archlinux... any tips? or is it just a normal touchpad?

I never tested that on WinXP. On Linux, the synaptics driver reports it as NOT multitouch capable.

I'm starting to think that the touchpad does not have a real multitouch support.

Hi,
well, the nc10 seems to have a multitouch touchpad. i think that in the youvid above shows windows vista, but dont know. i will check that out under ubuntu/archlinux next days, maybe it will work with linux.

bye

The Video shows Windows 7....

It runs nice on the NC10, performance-wise, but it sucks, because it is windows and it is worse then vista

the Synaptics touchpad DOES support multitouch! at least somehow: on windows xp, i use TwoFingerScroll all the time. it doesn't add much multitouch functionality as the name suggests, but you will love it.

it's much easier to use the whole (still small) touchpad to scroll (with two fingers) because the normal scroll area on the right side of the touchpad is hard to find without looking at it (there is almost no gap between the case and the touchpad).

it needed a little fine-tuning because apparently opera's scrolling works in another way than firefox' does.

i would love to see twofingerscroll for linux!
edit: i just found out that it should already work but doesn't.
you can check if it is enabled with
synclient -l | grep TwoFinger

Code:

sk@sk-nc10:~$ synclient -l | grep TwoFinger
    EmulateTwoFingerMinZ    = 280
    VertTwoFingerScroll     = 1
    HorizTwoFingerScroll    = 0

with symclient -m 50 you will see it doesn't recognize two fingers (the "f" column represents the number of fingers)

The next linux kernel has got patch on multitouch input support. Do not know (and understand) if that could bring multitouch support to the NC10's touchpad.

next? 2.6.30?

Yes... Do not remember where I have read the description.

This is the site (The H Open; The kernel log post date 1 june) with a link to the patches (look at Notebooks and input devices). I have not seen where is the short permalink...

Apparently multitouch is a work in progress... And already possible but experimental. See the link for details.

I really don't care about two finger scroll; I just want two-finger paste (middle mouse button). I'm used to this working out of the box on other laptops.

Now from what I've read on other forums the NC10 SE does not have multitouch. I don't have the SE, just the regular NC10. I have been able to get multitouch working on Windows.

However, when I look in dmesg, I see this:

Code:

$ dmesg | grep Synaptics
[   13.848255] Synaptics Touchpad, model: 1, fw: 7.2, id: 0x1c0b1, caps: 0xd04731/0xa40000

It's the cap bits that I'm interested in. According to the "touchpad interfacing guide" (you can find this on the synaptics website), the bit for capMultiFinger is bit 1 of byte 3:

Code:

irb(main):002:0> byte3 = 0xd04731 & 0xff
=> 49
irb(main):003:0> (byte3 >> 1) & 1
=> 0

which as best I can tell means the hardware does not support multifinger.

Two possibilities as I see it:

1) The newest synaptics hardware does not support multifinger through the same documented interface as the old hardware
2) The hardware does not support multifinger and is being emulated somehow on Windows.

I am curious about the bit after the '/'. Those are the capabilities from the extended query (0x09). Multiple (more than 4) button support is in byte 2 (bits 14..12), but I don't know what the 0xa4 in byte 1 is supposed to represent. Maybe it is for multitouch?

Opensuse seems to provide a more complete preference window. Is it into Karmic?
